DESCRIPTION:Speakers: Lena Heijkenskjöld (Institut für Kernphysik\, Joha
 nnes Gutenberg Universität Mainz)\nDecays of the light mesons $\\pi^0\\$\
 , $\\eta$\, $\\omega$\, and $\\eta'$ provide a unique laboratory to test f
 undamental aspects of hadron physics. Precision studies of such diverse to
 pics as the light quark mass ratio\, $\\pi-\\pi$ scattering lengths\, and 
 searches for physics beyond the Standard Model are possible. Additionally\
 , their Dalitz decays provide a way of measuring the electromagnetic meson
  Transition Form Factors (TFFs) in the time-like region. Precise knowledge
  of pseudoscalar TFFs is vital for the precision frontier of the Standard 
 Model as they are needed as experimental input in calculations of the hadr
 onic Light-by-Light contribution to the anomalous magnetic moment of the m
 uon.\n\n\nThe A2 tagged photon facility at the Mainz Microtron (MAMI) prov
 ides a high yield of light mesons produced by photo-induced reactions on p
 rotons. It makes the experiment ideal for high precision measurements of m
 eson decays. The experimental setup utilises the Bremsstrahlung distributi
 on of the A2 photon beam\, produced from the MAMI electron beam\, along wi
 th a system of detectors that nearly covers the full solid angle.\n\n\nThi
 s talk will highlight the recent contributions as well as ongoing studies 
 by the A2 collaboration in the field of light meson interactions.\n\nhttps
